Per-priority occupancy, measured every second until the fault:
[queues] p0=BUSY p1=- p2=BUSY p3=- p4=- nextReady=1
That single line kills the two leading theories. p3/p4 empty means nothing
above priority 0 is competing, so the pump is free to serve it -- no
starvation. nextReady=1 means PeekAtNextEvent always has a READY event, so
priority 0 is not holding a timed event whose alarm never comes due -- no
deadlock. What remains is refill: priority 0 is replenished as fast as the
pump drains it, ~143 events per simulated second.
It is also fully deterministic. Two runs of the same binary reported
pump=352/1499 at frame 1001 and 495/2643 at frame 2002, identical to the byte.
So 'crashes about half the time' was never a race -- it was comparing runs that
differed in binary or conf.
Only InterestManager::PostRendererEvent posts at priority 0 (it maps every
renderer event there while the app is not RunningMission), so naming the
message names the flooder. Application::Post now tallies priority-0 posts by
message ID and reports the busiest three. Notably, all three producers of
NotifyOfNewInterestingEntity are entity-CREATION paths, so if that ID dominates
then something is creating entities in a loop -- which would explain the
unbounded growth behind the fault as well as the hang.
pod_render_noskl.conf now carries the same probes, so one instrumented binary
can be run with the skeleton walk on and off. Walk-off runs are the only
configuration of ours known to reach 'Turning Plasma Score Display On'.
